This inventio rangement of railway- NOBLE, a sub- Great Britain, residing at of Lanof England, have inuseful Improvements (for which application 26,294, the foln has for its object an archair whereby a halfround sleeper can be used instead of a rectangular one. By this means two sleepers can be made by simply splitting or sawing a round log of the requisite size into into two with a centra and then slightly squaring t In the accompanying draw an end view metal applied the top face; Fig. 3 and 4, end vie iron or steel applie of my railway-chair to a sleeper or tomed and double-headed rails.

Referring first to halfround sleeper or chair B is made with a base B, side of which is of conca the shape of the segment of a circle,

fit onto the half-round surface of the ch it is made with two aws -headed rail D, witha wood typ enamely receive the double key E between adjacent jaw.

the chair need only sleeper and the spikes or Where it is ma In use be bedded onto the dogs F driven in.

de of wrought-iron or wroughtsteel, a part of the base B can have up, rail slits cut G, thus formed, turned between which the These can be hammered down onto the flanges of the rail D to hold it tight, and dogs H pass throug down flanges and through to hold the same t holding the base sleeper sleeper. The the sleeper ra the rail D as shown in Fig. 3, h the hammeredinto the ight, other dogs F of the chair tight on its spikes or dogs are driven into dially to the curvatur e of the base of the chair and of the sleeper itself, and they thus hold against a vertical upanddown shaking very much better than those spikes which are driven vertically downward. The other advantages of this chair are, first, reat economy in timber; second, the chair will still hold on the sleeper even if the spikes get loose; third, there is much less danger of the sleeper cracking under pressure of the driven spikes or dogs; fourth, the sleeper itself having its bottom fiat and its top round holds in the ground better than a rectangular sleeper does, as it is to a certain eXtent dovetailed into the ground, and, fifth, water drains off a rounded sleeper very much quicker than off a flat sleeper or a sleeper even slightly concave at the top, as there is no fiat or hollow space for water to lodge in. I

By my invention the necessity of providing a flat place in roundtopped sleepers, truly adzed and planed as a seating for flatbottomed chairs, is dispensed with. My chairs seat themselves on the sleeper without any such flat place being provided and provide a large bearing-surface of considerably greater area than the ordinary chairs.

I declare that what I claim is 1. In combination with a rail, and a tie or sleeper having a rounded top surface, of a chair or support provided with jaws to receive the rail, a base so shaped as to fit the contour of and seat itself on the tie or sleeper, and fastening means for fastening the chair to the sleeper radially to the curvature of the base of the chair and of the sleeper itself.

2. In combination with a rail, and a tie or sleeper having a rounded top surface, of a chair or support having a base cast in one piece with the jaws, said base being made concave on its under side to fit and seat itself on the rounded top surface of the sleeper.

3. In combination with a rail, and a tie or sleeper having a rounded top surface, of a chair or support having a base shaped to fit and seat itself on the rounded top surface of the tie or sleeper, a slit cut in said base and the tongue thus formed turned up so as to form a jaw against which the rail is fixed, and means for fastening the rail to the chair, and the chair to the sleeper.

4. In combination with a sleeper having a rounded top chair or support having a base and seat itself on the rounded top surface of the tie or sleeper, a slit cut in said base and the tongue thus formed bent over and hammered down onto the flange of the rail to hold it tight, and a dog or spike passed through Witnesses:

the hammered-down flange and through the WM. PIERCE,

rail and the sleeper to hold same tight THOMAS S. SHILLINGTON.

In Witness whereof I have hereunto signed my name, this 8th day of January, 1906, in the presence of two subscribing Witnesses.
